array_transff_freqslowness(coords, slim, sstep, fmin, fmax, fstep, coordsys='lonlat')[source]

Returns array transfer function as a function of slowness difference and frequency.

  • coords (numpy.ndarray) coordinates of stations in longitude and latitude in degrees elevation in km, or x, y, z in km
  • coordsys (str) valid values: ‘lonlat’ and ‘xy’, choose which coordinates to use
  • slim either a float to use symmetric limits for slowness differences or the tupel (sxmin, sxmax, symin, symax)
  • fmin (float) minimum frequency in signal
  • fmin maximum frequency in signal
  • fmin frequency sample distance
